Looking at the fourth-level mutant who slowly stood up, Yun Ye almost screamed in surprise.

Are you kidding?!

An infantry grenade that exploded close at hand didn't kill the flesh and blood of the mutant, if it weren't for seeing the grenade blow up several mutants around the fourth-level mutant, Yun Ye would have thought that this grenade was a parallel import.

Yun Ye substituted himself into the same situation, and then got a very sad fact.

I'm going to die!

It's also level four, why is the gap so big?

Fan Hua obviously didn't expect this situation, and was almost disemboweled, by the sharp claws of a mutant in front of him.

Thankfully, he recovered in time to shoot the mutant in the head as he quickly retreated.

The fourth-level mutant who stood up grabbed the two mutants beside him with two big hands like a fan, and threw the two mutants at Yun Ye and the other warrior like throwing stones.

Yun Ye, who was killing another mutant, was alarmed, and while slashing horizontally at the mutant in front of him, his footsteps twisted and slid to the left side, dodging the mutant that was thrown.

But the other warrior was not so lucky, as he raised his gun when he was thrown to the ground by another mutant thrown at him, biting him on the neck.

"Don!" Fan Hua could only scream in tears, but he couldn't save the warrior, because he still had to deal with the mutant who rushed forward in front of him.

The rest of the soldiers were the same, and could only let out an unwilling roar.

They are unwilling, they are angry, but, what can they do?

I could only watch the warrior fall in a pool of blood!

Even if he was as strong as Yun Ye, he could only watch as the warrior was slaughtered to the ground, and in front of him, there were more mutants than the remaining two.

No, you can't stay here, you have to leave as soon as possible!

Yun Ye roared angrily in his heart, and in the face of the constant influx of mutants, he also felt strained and exhausted.

He knew that if he was allowed to continue like this, none of the last three of them would want to leave.

Since there is a level 4 mutant, there will be more level 4 mutants, and maybe there will be a higher level mutant that hides in the shadows, ready to strike a fatal blow at any time!

One after another, mutants fell under Yun Ye's knife and the muzzle of the other two, and naturally, the three of them were more or less colored.

Yun Ye was slashed in the chest by a mutant's claw without relieving his breath between swinging the knife, but he dodged it in time, which prevented the tragic incident of being pierced in the chest by the mutant.

If only I could be faster in my knife skills, I could be more proficient in my knife skills.

It's too slow, it's too slow, it's too slow!

Yun Ye kept swinging his knife, and at the same time, he couldn't stop roaring in his heart.

In the face of the crazy swarming mutants, the speed at which he swung his knife now was too slow!

Just as Yun Ye kept swinging his knife to slash the mutants, a mechanical cold voice appeared in Yun Ye's mind.

"If the host meets the upgrade requirements, will it be upgraded?"

Although the voice was mechanical and cold, it was like the most beautiful natural sound in Yun Ye's mind.

"Yes!"

"Congratulations to the host for reaching level 5 and gaining two free attribute points and one skill point."

Yun Ye was overjoyed, and without the slightest hesitation, he directly upgraded that skill point to the proficiency of cold weapons.

But he overlooked a very important thing, and that thing was enough to ...... Fatal!

"Ahh......!!!h

Yun Yewu, who was wielding a knife, let out a terrible scream, holding his head with one hand, and his bloodstained face was full of hideousness.

Fan Hua was shocked, thinking that Yun Ye was seriously injured, so he hurriedly ran to Yun Ye's side and killed a mutant who wanted to take the opportunity to sneak attack for him.

Seeing this, the other soldier also hurried to Yun Ye's side to resist the attack of the surrounding mutants for him.

"Yun Ye, how are you?" Fan Hua quickly checked Yun Ye's body and found that except for a few wounds that were not deep or shallow, there were no fatal wounds on his body at all, but seeing that Yun Ye's face was hideous, and the painful appearance of the blue tendons on his forehead did not look like a fake, he thought for a while that he had not checked something, and hurriedly asked.

At this time, Yun Ye still had the heart to answer Fan Hua's words, he only felt as if his mind was about to be torn apart, and there were countless knowledge about the use of various cold weapons from the system and poured into Yun Ye's mind.

Enduring the pain in his mind as if it was about to explode, Yun Ye stepped forward with the only remaining bit of sanity, and the blade in his hand slashed wildly at the mutant, without a one-glance move, just constantly waving the knife and waving the knife.

Yun Ye couldn't bear the pain coming from his brain, so he had to find something to distract himself, and he urgently needed to find an outlet to vent the pain he had endured.

And there's nothing better than the mutants in front of you.

The catharsis was found, but it was the mutants in front of him, under Yun Ye's crazy slashing, stumps were constantly cut off, and heads were constantly in the air.

Yun Ye's series of actions made Fan Hua and the others stunned, obviously they had only endured great pain before, how could they be so alive now?

Although I don't know what happened to Yun Ye, in Fan Hua's opinion, this is a good thing.

At least that's a good thing for the current situation.

With the frantic Yun Ye opening the way in front of him, the speed of the three of them was raised, if it was just a turtle speed before, then now it is advancing at an almost normal speed.

The stump flew, and there were constantly mutants roaring angrily, wanting to kill Yun Ye who was opening the way in front, but all this was in vain, even if he could leave scars on Yun Ye's body, but before he could go any further, he was beheaded by Yun Ye.

And the fourth-level mutant had no follow-up after throwing out the two mutants, but just stood there like a mountain, as if it was resting.

It wasn't until Yun Ye and the others walked in that they found that the lower half of the fourth-level mutant like a small mountain had been almost blown up, one leg was missing, and the remaining leg was almost only left with the white bones, and there were black cracks on the bones, which looked like they might shatter at any time.

No wonder this beast has been standing here. Fan Hua, who saw the mutant situation, muttered quietly in his heart.

Yun Ye, who was already red-eyed, saw the fourth-level mutant standing in place, and immediately roared angrily, and was about to rush forward to kill him with his knife, but fortunately he was stopped by Fan Hua in time.

"You're crazy!" Fan Hua yelled at Yun Ye's viscous and bloodstained clothes.

After such a roar, Yun Ye was a little more sober, he hurriedly added a little to his spirit, and after a warm current, he felt that his brain was clearer.

This is also an inevitable situation, after a period of crazy slashing and venting, Yun Ye felt that his mind was no longer so painful, and the feeling of wanting to burst his brain was slowly fading, at most he was just a little unconscious, after Fan Hua's roar, his mind was roared back, and people naturally came to their senses.

"I'm ...... What's wrong? Yun Ye looked at Fan Hua, who was only a stone's throw away from him, in confusion.

Fan Hua was choked up by the question, you actually asked me what's wrong with you? What the hell do I want to know what's wrong with you?!

This is not to blame Yun Ye, after that period of huge pain in his brain as if it was about to be burst, coupled with a long period of killing, his mind obviously has not completely come back to his senses, and people are naturally a little confused.

However, Fan Hua knew that now was not the time to discuss this, and the top priority was how to kill this mutant and escape from here.

Although the fourth-level mutant couldn't move, that didn't mean he couldn't attack.

He grabbed the two mutants again and threw them at the trio.

However, this time, the three of them were prepared, and they quickly dodged the two flying mutants.

Fan Hua, who had just dodged the flying mutant, immediately raised his gun to shoot, and the muzzle of the black hole was aimed at the watermelon-like head of the fourth-level mutant, and he pulled the trigger fiercely.

A gunshot exploded, and a bullet erupted, but this shot didn't kill the fourth-level mutant.

The moment Fan Hua's muzzle was aimed at his head, he raised one arm and crossed it in front of his head.

So that shot actually hit the mutant's thick arm.

Fan Hua was unwilling, and fired a shot at his head again, this time it did hit the head of the mutant, but it was not the head of the fourth-level mutant, but the head of the mutant who was caught by the fourth-level mutant and blocked in front of him.

The dull gunshots continued to sound, but the mutant was unmoved, only using one mutant to protect his head, allowing the bullets to hit the rest of his body, and the other hand danced wildly like crazy, and for a while actually blocked Fan Hua and the others in place.

"I'm coming!" Yun Ye had already rushed out when he shouted.

Seeing this, Fan Hua also immediately understood, raised the muzzle of the gun, pointed at the head of the mutant and hit it violently.

Yun Ye sprinted rapidly, making a mighty sound, and then leaned over to dodge, and the dancing claws of the mutant grazed Yun Ye's face.

Yun Ye rushed to the mutant's approach, and instead of choosing to attack his head, he slashed at his boneless leg.

Click, no accident, how could the bone legs, which were already full of cracks, withstand Yun Ye's sharp knife, and immediately shattered under the knife, and the bones were all over the ground.

"Whew!"

The mutant let out a wail, a claw grappling at the wall next to it to prevent it from falling, grabbing it out of a slender furrow, revealing the rusty steel bars inside.

It's a pity that all this is in vain, how can he stand without legs?

The moment he caught the mutant and fell to the ground, Yun Ye immediately rushed to him.

The sword flashed, like thunder falling from the sky, and a wail represented the end of a life.

"Kill a level 4 mutant and gain ten points of experience."
